Bossa

Bossa is an open-source software framework for distributed thinking - the use of volunteers on the Internet to perform tasks that use human cognition, knowledge, or intelligence.

Bossa minimizes the effort of creating and operating a distributed thinking project. It provides a project web site, hosted on your Linux server, where volunteers go to perform tasks and to interact with other volunteers. All you need to supply are PHP scripts to generate, show, and handle tasks.

Bossa helps you deal with the variance of volunteer skill. It maintains estimates of the skill level of volunteers, and ensures that, for each task, there is a 'consensus' of compatible results among a sufficient set of volunteers.

Typically you'll want train volunteers; this can be done using Bolt, a framework for web-based training that integrates with Bossa.
